UVES and HIRES high-resolution spectra of Comet 9P/Tempel 1 are used to investigate the impact and rotational light curves of various species with a view toward building a simple model of the distribution and activity of the sources. The emission by OH, NH, CN, C[SUB]3[/SUB], CH, C[SUB]2[/SUB], NH[SUB]2[/SUB], and OI, are analyzed, as well as the light scattered by the dust. It is found that a simple model reproduces fairly well the impact light curves of all species combining the production of the observed molecules and the expansion of the material throughout the slit. The impact light curves are consistent with velocities of 400 600 m/s. Their modeling requires a three-step dissociation sequence ``Grand-Parent --> Parent --> Daughter'' to produce the observed molecules. The rotational light curve for each species is explained in terms of a single model with three sources. The dust component can however not easily be explained that way. [less ▲]

Based on a thorough review of the literature as well as floristic surveys undertaken over 20 years, a checklist of the bryophytes of Corsica, a mountainous western Mediterranean island, is presented. The occurrence of 17 liverwort and 44 moss species is documented for the first time from Corsica. As a result, the Corsican bryoflora includes 540 species: 148 liverworts, three hornworts and 389 mosses. Among the species reported, seven liverwort and 17 moss species are red-listed in Europe. By contrast with angiosperms, no bryophyte is endemic to the island based on traditional, phenetic species concepts. The number of new species reported here indicates that Corsica is exceedingly under-recorded bryologically. A better knowledge of the distribution, frequency and ecology of bryophyte species on the island is thus an absolute prerequisite in order to propose appropriate conservation measures in this Mediterranean environment that is, at least locally, severely threatened.

The prevention of type 2 diabetes and of cardiovascular diseases is a major public health objective. Obviously life-style changes play a major role in this strategy. The Finnish Prevention Study recently demonstrated that the remarkable diabetes prevention observed after a 4-year lifestyle intervention is maintained after a further 3-year period of follow-up without prolongation of the active intervention. Such a reminiscent effect may also be observed in the prevention of cardiovascular diseases with various pharmacological interventions: an ACE inhibitor (HOPE), a statin (4S), a fibrate (Helsinki Heart Study) or an intensive insulin therapy in type I diabetic patients (DCCT-EDIC). These intriguing results argue for a long-term memory of previous therapeutic interventions in cardiovascular prevention. [less ▲]

PURPOSE: The first reports that ionizing radiation (IR) induces rapid and persistent activation of transforming growth factor beta1 (TGFbeta) were nearly two decades ago. Subsequent studies have shown that TGFbeta is a major mediator of cellular and tissue responses to IR and have revealed novel facets of its complex biology. RESULTS: We and others have recently shown that inhibition of production or signaling of TGFbeta in epithelial cells modulates radiosensitivity and impedes activation of the DNA damage response program. The primary transducer of cellular response to DNA damage caused by ionizing radiation is the nuclear protein kinase ataxia telangiectasia mutated, whose activity is severely compromised when TGFbeta is inhibited. Thus, in conjunction, with its well-recognized contribution to normal tissue fibrosis, the role of TGFbeta in the genotoxic stress program provides a previously unsuspected avenue to modulate radiotherapy. CONCLUSIONS: We hypothesize that identification of the circumstances and tumors in which TGFbeta manipulation enhances tumor cell radiosensitivity, while protecting normal tissues, could significantly increase therapeutic index.

Thiazolidinediones (TZDs) are used as insulin sensitizers in the treatment of type 2 diabetes, but are associated with an increased risk of congestive heart failure (CHF). The odds ratio of ICC was 1.43 (pioglitazone vs placebo) in diabetic patients with high cardiovascular risk in the PROactive trial while it averaged 1.22 (rosiglitazone vs metformin) and 2.20 (rosiglitazone vs metformin) in the ADOPT study. In the interim analysis of the ongoing RECORD trial, the odds ratio averaged 2.15 (rosiglitazone vs metformin or sulfonylureas). In four real life registries, the relative risk of CHF with TZDs varied between 1.06 and 1.76 (between 1.10 and 1.44 combined with insulin) as compared to a treatment without TZDs. Such higher CHF risk should be appreciated according to the potential benefits of glitazones in the management of type 2 diabetes. [less ▲]

Two quantitative trait loci (QTL) affecting female fertility were mapped in French dairy cattle. Phenotypes were non-return rates at 28, 56, 90 and 282 days after insemination. On chromosome 3, a QTL was significant at 1% for non-return rate at 90 days, suggesting that it affects early fertility events. An analysis of SLC35A3, which causes complex vertebral malformation, excluded this gene from the QTL interval. On chromosome 7, a QTL was almost significant (P = 0.05) for non-return rate at 282 days. This QTL was associated with abortion and stillbirth problems. Use of appropriate phenotypes appeared important for fine-mapping QTL associated with fertility. [less ▲]

Perfluorooctane sulfonate (PFOS) and other perfluorinated alkylated substances (PFAS) were determined in liver, kidney, muscle, brain, and blubber samples of 31 harbor porpoises (Phocoena phocoena relicta) of different age and sex stranded along the Ukrainian coast of the Black Sea. In all individuals and in all tissues, PFOS was the predominant PFAS, accounting for on average 90% of the measured PFAS load. PFOS concentrations were the highest in liver (327 +/- 351 ng/g wet wt) and kidney (147 +/- 262 ng/g wet wt) tissue, and lower in blubber (18 +/- 8 ng/g wet wt), muscle (41 +/- 50 ng/g wet wt), and brain (24 +/- 23 ng/g wet wt). No significant differences could be determined between males and females, nor between juvenile and adult animals (p > 0.05). Perfluorononanoic acid, perfluorodecanoic acid, perfluoroundecanoic acid, and perfluorododecanoic acid could be detected in liver tissue of approximately 25% of the individuals. Perfluorobutane sulfonate, perfluorobutanoic acid, and perfluorooctanoic acid were not detected in any of the porpoise livers. Although we investigated a potential intraspecies segregation according to the source of prey, using stable isotopes, no statistically significant correlation between PFOS concentrations and stable isotopes could be determined. It is, however, noteworthy that the contamination by PFOS in the Black Sea harbor porpoises is comparable to levels found in porpoises from the German Baltic Sea and from coastal areas near Denmark and, therefore, might pose a threat to this population.

Infectious respiratory diseases also called ‘cat flu’ are nowadays one of the most relevant areas of feline medicine. Epidemiologic surveys revealed that 80% of the cases are due to feline calicivirus and Felid herpesvirus 1 (FeHV-1). FeHV-1 is an alphaherpesvirus that has a worldwide distribution in cat population. It is responsible for feline viral rhinotracheitis. This disease can be acute, chronic or latent. It is characterized by fever and respiratory or ocular signs among which conjunctivitis and keratitis are the most common. Severe cases can cause complete blindness of the cat mostly following repetitive reactivations. Latent viral carriers are epidemiologically important because they are the main source of infection to susceptible cats. Nowadays no vaccine can prevent infection. At best, available vaccines help to reduce clinical signs but fail to prevent establishment of latency or reactivation. Consequently, feline viral rhinotracheitis still represents a major problem in domestic cats. This review focuses on the current knowledge about feline viral rhinotracheitis and its etiologic agent, FeHV-1. [less ▲]
